I use Greenshot now after using PrintKey for many years. Greenshots works good. But when you want to save a screen picture you have to press on the OK-button, in Greenshot quality window, with the left mouse-button. It should be very usefull when the OK-button is active and that only pressing the Enter key is enough to save the picture. Pressing the Enter-key goes faster than selecting and pressing the OK-button. The Destination window after the screen selection can be used by pressing on the first letter of a line, that feature is usefull.
But may be there is already a solution for this activition of the OK-button?
